Congratulations on starting your homegrown Blue Oyster mushrooms! Now the fun(gus) begins!
If your bag is not fully colonized you are in for a real treat! Over the next few days you will see those white tufts of mycelium expand their reach across the entire bag. Be sure to take a look at your Kit every day; the mycelium will expand faster than you might think!
Listed below are a few care instructions so that you may ensure the successful cultivation of your Blue Oyster Mushroom Kit. It is crucial that you provide your mycelium with a hospitable environment.
Storage during colonization:
Store your bag in a dark room between 70 F and 80F. Mycelium is sensitive to ultraviolet radiation and high temperatures- exposure to too much UV radiation or heat will stunt growth or kill the mycelium. Mycelium breathes oxygen and exhales carbon dioxide - just like us! The filter patch on your kit will allow gas exchange without letting in any contaminants.
Storage during fruiting:
Once your bag reaches 100% colonization (this means that all of the substrate is covered in mycelium) cut off the top of the bag above the white patch. Lay your bag on its side in a location that receives dappled or indirect sunlight - not direct sunlight and not complete darkness. Twice daily spray or flick with your fingers enough water on the inside of the bag to leave a few droplets of water - this will raise the relative humidity of the bag and tell the mushrooms that conditions are ideal for fruiting!
Harvesting your Blue Oysters:
Be sure to take a look at your Blue Oyster Kit every day! Fruit bodies will double in size every 24 hours under ideal conditions. You will know to harvest your oysters when the edges of the cap just begin to turn up and out.
After your first harvest, continue to keep the humidity high in your bag - the mycelium will continue to fruit 2-3 more times! Once your kit has finished its last flush, break up the substrate and compost it to add to your soil health, then recycle the bag.
